APPLICATIONS
The 2A_XSR series are specially designed
for applications where a group of polar power
supplies are isolated from the input power
supply in a distributed power supply system on
a circuit board.

These products apply to:
1) where the voltage of the input power supply
is fixed (voltage variation ≤±5%);
2) where isolation is necessary between input
and output (isolation voltage≥1000VDC);
3) where the regulation of the output voltage
and the output ripple noise are demanded.
